๐งญ Introduction | Is sunscreen really unnecessary in autumn?
As the temperatures gradually cool, many parents assume that "sunscreen season" is over.
But lower temperatures don't necessarily mean reduced UV rays.
According to the American Academy of Dermatology (AAD), even in autumn, the UV Index (UVI) can reach a moderate to high level of 5-6, enough to cause long-term damage to baby's sensitive skin.
๐ค Scientific Explanation: UV intensity depends primarily on the angle of the sun and the thickness of the atmosphere, not temperature.
In autumn, sunlight can still penetrate clouds, especially in the afternoon when outdoor activities are frequent, exposing baby's skin to UV rays.
โ๏ธ Scientific Basis: The Hidden Threat of UV Rays in Autumn
The World Health Organization (WHO) states that sun protection measures are necessary when the UV Index is 3 or higher.
Data from the U.S. Environmental Protection Agency (EPA) show that the average UV Index for September and October remains between 4 and 7. Even on cloudy days, up to 80% of UV rays can still penetrate clouds.
In other words, while autumn's UV rays are "gentle," the damage is long-term and cumulative.
Baby's skin barrier is particularly underdeveloped, making UV rays more susceptible to dryness, sunburn, pigmentation, and even DNA damage.
๐ฉฑ Practical Tip: Can babies still wear swimsuits in autumn?
Many parents wonder, "Should I put away my summer swimsuits?"
In fact, if chosen wisely, spring and summer sun-protective swimsuits can still be worn in autumn.
โ The following situations are particularly suitable:
Autumn travel (such as in tropical or southern regions): Temperatures remain high, so swimsuits can still be worn.
Heated pool swimming lessons: The water temperature is comfortable, and sun-protective swimsuits can still provide skin protection.
Outdoor play, sandpits, and beach walks: Pairing with a layer of cardigan or sweater provides both sun protection and warmth.
๐งต Material Selection Guide: How to Choose a Sun-Protective Swimsuit for Fall?
The key to autumn wear is finding the right balance between breathability, warmth, and sun protection.
| UPF Index | ย Choose UPF50+ certified materials, which block over 98% of UV rays. |
| Fabric Composition | Polyester + Spandex, primarily for stretch and quick-drying properties. |
| Weave Density | Tightly woven fabrics offer better sun protection; avoid thin or mesh designs. |
| Comfort | Choose a soft, non-irritating lining to protect your baby's sensitive skin. |
| Stretchable Design | Half-zippers, one-piece styles, and bottom buckle designs make diaper changes and dressing easier. |
